Secured on the shaft portion 3a is a clutch washer 9a to which the spring 9 is secured and the opposite end of the spring 9 is engaged in ratchet relation with the side of the gear 8 so that when the plunger member 1 is moved inwardly by pressure on the head la, the shaft 3a is revolved and at the same time the valve i is rotated to open the opening 21). The shaft 3a is provided with extended annuuar portions 31) and 3c in which are secured loop shaped wire members 311 which are U-shaped and the transverse portion of which extends adjacent the inner surface of the casing 2, and interposed between these members 3d are other shorter similar members Se which provide agitation some distance from the surface of the member 2, all as shown best in Fig. 2 of the drawing. Secured to he one side of the auxiliary casing I2 is a. cylindrical plunger casing it which extends outwardly some distance from the one side of the member l2 and is provided in its extended end with a plug Edd which is provided with a central hole lilb which forms a support for the plunger member 1. This plunger member I is provided with a washer id. secured thereto and between said washer Id and the side wall of the member if! and around the plunger member l is a compression spring I l which tends to carry the Washer ld outwardly carrying with it the plunger members l when released and at the same time closing the valve 4. The member it is provided with an extending flange ldb which is adapted to be engaged by the fingers while the thumb engages the knob 30 for pressing the plunger and operating the valve and agitating. The auxiliary casing I2 is provided with a plate cover l3 secured thereto by means of lugs 52b, 22c, and 52d and forming a covering for enclosing the. agitator and valve operating mechanism.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination, and arrangement, but desire to include in the scope of my invention the construction, combination, and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a powder dispenser, a casing provided with a semi-circular bottom portion provided with a slot centrally at the lower extremity, a revoluble valve arranged to cover and uncover said slot, means positioned at the side of said ca ing for revolving said valve, including an arm member secured to said valve, and link and plunger means operatively connected with said arm, said casing opened at its upper side and provided with a beaded portion adapted to receive a powder receptacle at one end.

2. In a powder dispenser, a casing provided with a semi-circular bottom portion provided with a slot centrally at the lower extremity, a revoluble valve arranged to cover and uncover said slot, means positioned at the side of said casing for revolving said valve, including an arm member secured to said valve, link and plunger means operatively connected with said arm, an agitator revolubly mounted in said casing including cross members positioned to revolve adjacent the inner surface of said casing at the lower side thereof, means connected with said agitator engageable by said plunger for operating said agitator simultaneously with the operation of said valve, said casing opened at its upper side and provided with a beaded portion adapted to receive a powder receptacle at one end.

3. In a powder dispenser of the class described, a casing provided with a semi-circular bottom portion, a slot in the lower extremity thereof extending across the same, an elongated revoluble valve revolubly mounted to open and close said slot, arm, link and plunger means for operating said valve into open and closed position, an agitator revolubly mounted in adjacent relation with the inner surface of the semi-circular portion of said casing, gear and shaft means connecting said agitator with said plunger means.

4. In a powder dispenser of the class described, a casing provided with a semi-circular bottom portion, a slot in the lower extremity thereof extending across the same, an elongated revoluble valve revolubly mounted to open and close said slot, arm, link and plunger means for operating said valve into open and closed position, an agitator revolubly mounted in adjacent relation with the inner surface of the semi-circular portion of said casing, gear and shaft means connecting said agitator with said plunger means, a casing for said plunger means, and spring means in connection with said plunger means tending to force said plunger means outwardly when released after inward pressure thereof.

5. In a powder dispenser of the class described, a casing provided with a semi-circular bottom portion, a slot in the lower extremity thereof extending across the same, an elongated revoluble valve revolubly mounted to open and close said Slot, arm, link and plunger means for operating said valve into open and closed position, an agitator revolubl mounted in adjacent relation with the inner surface of the semi-circular portion of said casing, gear and shaft means connecting said agitator with said plunger means, a casing for said plunger means, springs means in connection with said plunger means tending to force said plunger means outwardly when released after inward pressure thereof, and an auxiliary casing enclosing said arm, link and plunger means.

6. In a powder dispenser of the class described, a casing provided with a semi-circular bottom portion, a slot in the lower extremity thereof extending across the same, an elongated revoluble valve revolubly mounted to open and close said slot, arm, link and plunger means for operating said valve into open and closed position, an agitator revolubly mounted in adjacent relation with the inner surface of the semi-circular portion of said casing, gear and shaft means connecting said agitator with said plunger means, a casing for said plunger means, springs means in connection with said plunger means tending to force said plunger means outwardly when released after inward pressure thereof, an auxiliary casing enclosing said arm, link and plunger means, and clutch means in connection with said agitator and said gear.
